I have installed Zimbra Connector for Outlook and when I started my Outlook, it asks for 'Zimbra Server Configuration Settings', so I have entered all the details such as Server Name, Email Address & Password and when I click OK, I am getting the following error

Zimbra Authorization Failure

"""Your account could not be validated against the Zimbra server. Please make sure you are online, and that you entered the correct information.""""

Do anyone have any idea about this error ? ... since I gave the correct information and email details.
